PENCIL ATTACHIYIENT FOR FOUNTAIN PENS.

Application filed November L', 1923. vSerial No. 672,359.

This invention relates to a combination4 pen and pencil and more particularly to a pencil attachment for fountain pens as set forth in my copending application for Datybe engaged by y"the ingers' of the. user forcnt'tiledf/iugust 30, i923, SerialNo. 660,185. rllhe primaryy object oi this invention is to provide a unitary structure which may be readily attached to the barrel of a fountain pen and will properly feed the lead when operated in a 'very simple manner.

Anobject of the invention is the combination and arrangement of parts whereby the cost of manufacture will be greatly reduced. A feature of my invention -is'the novel manner of connecting parts so that they may be readily disconnected.

"W ith these and other objects in view the invention will be better understood from the following detailed description takenin connection with the accompanying drawing wherein:

Fig. 1 is a side'elevation of a pen struc1 ture showing' the pencil attachment at one end ther-soif.

Fig. 2 is an enlarged improved attachment. l

, 3 is a sectional view ofiE Fit., 2.

t is a side elevation o16 the tube and its associate-parts.

Again referring to the drawing illustrat ing` one of the many constructions of my invention the numeral 1. designates a pen structure Whichmay be of any of the Well known designs having one end portion 2 open so that my improved pencil structure may be quickly and readily attached thereto. My improved pencil structure consists sectional view ot my on the line 'SW3 oi a sleeve 3 removably fitted in the open end 2 but `frictionally held against rotation. lotatably mounted IIn the sleeve'i'is the plug 4 having a ringypfflittion. 5 exposed so as. to

Iturning the plug Within the sieev'e.- AThis plugfjalso includes an annular iiangev '6 to Awwhich isfifrictionally attached the shell 7 ivliich has a. lead opening My improved leady .projecting means `9 'consists of a tube 10 secured to the-plug 4 and provided with a longitudinally ,extending slot 11. The inner end. of the sleeve 3 is provided with an inwardly extending annular guide iange as illustrated in F ig. 2. The tube 10 has an enlarged .upper end which frictionally en;

' the inner Wall of the barrel il on the plug 4. VThis barrel 4e extends inwardly from the plug opposite the flange l and is rotatably mounted Within the sleeve 3l as shown in Figi "2. A spiral member 1.2 provided which maybe in the form of a'."coil spring having one'lend attached'to the collar 13 'as indicated at 14. Thiscollar 13 in turn is attached to the sleeve 3 vby the screw l5. The inner` end of the barrel 4 is provided With an inturned annular flange which is adapted to rotatably engage Ithe collar 13 whereby the `barrel 4: and the tube 1.0 will rotate independentfof the sleeve 3 upon the Itfflvill turning movement of the ring 5. be noted that the collar 13 has a reduced portion which engages the inner perimeter of the flange on the inner end of the sleeve 3 and receives the screw 15 Which connects the collar ,13 tothe sleeve 3. A ring 16 is interposed betweenv the collar 13 and adjacent the end of the split tube. A follower 17 operates Within the spiral member against the end of the lead and has a lug 18 moving betweenv the convolutions of the spiral member and in the slot 11, and thus it will be seen. that by turningr the ring 5 thereby plug d and tube 9 .will be turned l'or moving the follower along the spiral member and thereby -force lead through the lead openingr 8. It Will-be noted the parts may be quickly attached to the end ofthe barrel ci' a pen structure and the'various parts may be disconnected from each other. Itwill also be noted the parts may be assembled so as to reduce the'cost of manufacture.

It is, of course, to be understood that the exact shape and manner of connecting the parts ma.' be changed at vvillv Without departing rom the spirit of this invention,

therefore, I do not desire to he limited in any manner except as set forth in the claims hereunto appended.

Having thus described my invention What I claim is: n

' 11.111 combination with. .a fountain pen structurehaving one end open, a sleeve lit-4 ted in said open-end, a rotative plug, a bai`- rel formed on the pluyangil disposed within the sleeve for rotative movement independent o" the sleeve, a poitml by sind plug', :L tulle in ille slnll', un enlzu'g; il poi'iion zit tlm inner ond ol' the lulio ll'ietiouzilly engaging the' inner will ineens carried by the tubo loi' :feeding a. loud tliexetlnxongli upon rotation oil the plug.
